Fluorinated compounds are effective mineralization agents for the fabrication of plate-like α-AlO. However, in the preparation of plate-like α-AlO, it is still an extremely challenging task to reduce the content of fluoride while ensuring a low synthesis temperature. Herein, oxalic acid and NHF are proposed for the first time as additives in the preparation of plate-like α-AlO. The results showed that plate-like α-AlO can be synthesized at a low temperature of 850 °C with the synergistic effect of oxalic acid and 1 wt.% NHF. Additionally, the synergistic effect of oxalic acid and NHF not only can reduce the conversion temperature of α-AlO but also can change the phase transition sequence.

Nanogold is an emerging material for enhancing surface-enhanced Raman scattering (SERS), which enables the detection of hazardous analytes at trace levels. This study presents a simple, single-step plasma synthesis method to control the size and yield of Au nanoparticles by using plasma-liquid redox chemistry. The pin-based argon plasma reduces the Au precursor in under 5 min, synthesizing Au spherical particles ranging from ∼20 nm at 0.

Article Synopsis
- BiVO is a stable photocatalytic material but struggles with photocatalytic activity under visible light; this study explores using surfactants to improve its efficiency for degrading tetracycline (TC).
- The research shows that surfactant-modified BiVO, especially BiVO-CTAC with a specific morphology, enhances light absorption and reduces the energy band gap compared to unmodified BiVO.
- The findings indicate that the surfactants influence the formation and structure of BiVO, leading to better charge separation and increased degradation efficiency of TC, highlighting a new method for synthesizing effective photocatalysts.
